Jurassic Ocean


Jurassic Ocean
200 to 145 million years ago Reptiles didn’t just live on land. Massive prehistoric monsters ruled the Jurassic oceans as well

Plate movement continued to reshape the continents and widen the oceans during the Jurassic period. The separation of the northern and southern parts of the Pangaea supercontinent continued into the Jurassic period, making the Tethys Ocean considerably larger. This ran in an east-west direction, which had a significant effect on the ocean flora and fauna. As such, fossils found in Western Australia were remarkably similar to those found on the southern coast of England.
The oceans were a fiercely fought-over battleground, with large marine reptiles such as the Plesiosaurus dominating the shallower waters. With its stocky torso, four large flippers, an extremely long neck and a tiny skull filled with small teeth, the Plesiosaurus was an accomplished predator of fish, squid and other relatively small, fast-moving prey. Moving further out to sea, other sauropterygians, such as the Liopleurodon, ruled the waters.
This reptile reached lengths of up to 10 metres and boasted a streamlined body that allowed it to soar through the water using its four paddle-like limbs. It could devour sizeable aquatic reptiles and large fish; in the survival of the fittest, this creature was a very prolific predator.
